QUATERNARY FAUNA OF GIBRALTAR. 111 
10":7 in length, the proximal end 1" x 2:9, and the distal 1-0 x 1'"5, the least circum- 
ference of the shaft is 3-0, and the perimetral index is -280. In @. barbarus the length 
of the radius is 9:2, the proximal end measures 0!"9 x 1"8, and the distal 1-2 1!"55, 
the least circumference of the shaft 2-8, and the perimetral index °304. 
It is needless to point out the close similarity in the proportions of these bones. 
7. Metacarpal. 
Of the metacarpal several specimens occur, but none entire. 
1. The lower half of the left metacarpal, about 4-6 long, in which the distal arti- 
cular end measures 1":1 x 1:6, and the least circumference is 2/9. 
2. A proximal portion, not improbably belonging to the same bone; the length of 
the fragment is about 5'6, and the proximal extremity measures 1!:21"-6. To this 
metacarpal is attached the entire set of carpal bones, somewhat crushed and dislocated, 
but remaining in connexion with the corresponding radius. 
3. In another specimen the proximal articular end measures 1-2 x 1-5. 
4. We have the right and left metacarpals of a young Deer, the epiphyses being 
detached in both. The more perfect measures as it is (that is to say, from the summit 
to the epiphysial surface) 8'"2; the proximal end is 1-0 x 1'-4, and the least circum- 
ference is 2-6. If an inch be added for the epiphysis, the entire length of the bone 
would be about 9-2, and the perimetral index -283. These specimens, which were 
found at the depths of 20 and 30 feet in the black mould, must probably be referred 
to the human period. One is coated with a thin film of stalagmite; but the other is 
not; and neither of them is sun-cracked. 
In the C. elaphus above cited the metacarpal is 9-4 long, the proximal end measures 
1"-0x1'"4, the least circumference 2'-3, and perimetral index is -244. In ©. barbarus 
the length of the metacarpal is 8'"4, the proximal extremity 1/0 x 1'"4, the distal 0-9 
x14, the least circumference of the shaft 2’:1, and the perimetral index °250. 
These figures are sufficient to show that the Gibraltar metacarpals, like the other 
bones, accord very closely with those of C. elaphus, the only difference worthy of note 
being, perhaps, that they are a little thicker. 
8. Femur. 
The only distinctly recognizable specimens of this bone are :— 
1. Two fragments of the upper end, one exhibiting the head and great trochanter 
entire ; in the other the greater part of the latter process is wanting. One of the bones 
is of a larger form than the other; in it the proximal end (including head and tro- 
chanter) measures 1!""3 x 2'"2, the former number denoting the diameter of the articular 
head itself. 
In the smaller specimen, which is nevertheless quite mature, the diameter of the 
head is 1-2. In the strongly pronounced pyriform shape of the head and its size, in
